Thanks Where is the model number? I see 3462 and a bunch of P/N numbers on the bottom , unpluggling doesn't help. Will the comcast remote work with this router? Is it common for comcast routers to crap out? Why does my iphone go from wifi to 3G on its own?

Do you mean the router must be on in order to use the remote? Is this remote for cable TV? Was the remote given to you from comcast? If you turn off the router, does the remote work? If the remote requires the router, then you would need to get the replacement router from comcast as it's specialized for comcast cable.

Do you mean only your iPhone's Wi-Fi has issue? If that's the case, then try: Please press and hold both the Power button and the Home buttons together on the iphone for at least 10 seconds, until the Apple logo appears, then wait a bit,, then go to Settings, General, Reset, Reset network settings. Then go to Settings, Wi-Fi, then reconnect to your wi-fi/wireless network name and check.
